<P>PROBLEM TO BE SOLVED: To provide a power supply system capable of avoiding power shortage and wasteful power supply. <P>SOLUTION: The power supply system 100 includes a server system 110 and a plurality of power control systems 120a, 120b. The each power supply system switches between a power reception state that receives electric power from an electric wire network and a power transmission state that supplies the electric power to the electric wire network. The server system 110 establishes a communication session for communicating between a controller for the transmission side power control system 120b and a controller for the power reception side power control system 120a (111). The controller for the power reception side power control system 120a transmits a transmission state setting instruction through the communication session (121) and sets its state to the power reception state (122). The controller for the transmission side power control system 120b sets its state to the transmission state upon reception of the transmission state setting instruction (123). <P>COPYRIGHT: (C)2012,JPO&INPIT |
